Our nails can tell us a lot about our health. Changes in their colour, texture, or shape can indicate an underlying disease or vitamin deficiency. Some nail abnormalities are harmless, but it's always good to consult a doctor or dermatologist if you notice anything unusual. For example, non-uniform white spots or lines on the nail, known as leukonychia, are usually the result of minor trauma and are harmless. However, they can sometimes be associated with poor health or nutritional deficiencies. Similarly, vertical ridges are common as people age, but deep grooves or gaps that run across the nail, known as Beau's lines, can indicate malnourishment or a disease that causes a high fever, such as measles. Yellow nails are commonly caused by a fungal infection, but they can also indicate a more serious condition in rare cases, such as thyroid disease or diabetes.

What You'll Learn
White spots or lines on nails
White spots or lines on your nails are usually harmless and are rarely a sign of a serious medical condition. This condition is called leukonychia, derived from the Greek words "leuko" (white) and "onyx" (nail). It is characterised by a whitening of parts of the nail plate in the form of small white dots or lines.
Leukonychia can be classified into two types: true leukonychia and pseudoleukonychia. True leukonychia is caused by damage to the nail plate or matrix, resulting in trapped air within the nail plate and a subsequent loss of transparency. These white spots or lines do not disappear with pressure. Pseudoleukonychia, on the other hand, appears as flaking on top of the nail and is often caused by fungal infections.
The most common cause of leukonychia is physical injury or trauma to the nail matrix, which can occur from various activities such as nail-biting, manicures, or accidents involving doors or windows. Certain medications, such as chemotherapy drugs and long-term antibiotics, can also cause leukonychia. Additionally, mineral deficiencies, particularly zinc and calcium deficiencies, can contribute to the appearance of white spots or lines on your nails.
In rare cases, leukonychia may indicate an underlying medical condition. For example, "half-and-half nails," where half of the nail is entirely white, can be a sign of kidney disease. Muehrcke's lines, characterised by transverse or longitudinal white lines, may indicate a deficiency in albumin protein. It is important to note that nail changes are rarely the first sign of a medical condition, and many abnormalities are harmless. However, if you are concerned about the appearance of your nails, it is recommended to consult a doctor or dermatologist for a thorough evaluation.

Yellow nails
Vitamin or mineral deficiencies can also cause nails to appear yellow, and introducing a multivitamin supplement may help. Persistent yellow nails can also be a symptom of underlying health conditions such as thyroid disorders, psoriasis, diabetes, rheumatoid arthritis, or chronic lung conditions. In rare cases, yellow nails can indicate skin cancer or a rare condition called yellow nail syndrome, which is characterised by yellow, thickened, and curved nails, as well as slowed or stopped nail growth, and respiratory or lymphatic issues.
If you are concerned about the appearance of your nails, it is important to consult a doctor or dermatologist, as nail abnormalities can provide clues about your overall health.

Spoon-shaped nails
While spoon-shaped nails are not always indicative of an underlying health issue, they can sometimes suggest the presence of a systemic disease. For example, in the absence of trauma or psoriasis, onycholysis (separation of the nail from the nail bed) may indicate hyperthyroidism. Similarly, spoon-shaped nails accompanied by other symptoms such as connective tissue disorders or lupus erythematosus, can prompt further investigation for potential conditions such as iron deficiency or hemochromatosis.
The occurrence of koilonychia has been linked to various factors, including occupational hazards such as constant exposure to petroleum-based solvents and nail-patella syndrome, an autosomal-dominant condition that includes skeletal abnormalities, among other symptoms. Additionally, spoon-shaped nails are commonly observed in newborns and toddlers, especially in the great toenails, and are considered a normal variant that often resolves as the child grows.
It is important to note that nail abnormalities, including spoon-shaped nails, are not always indicative of a serious medical condition. However, if you are concerned about the appearance of your nails or notice any other symptoms, it is recommended to consult a doctor or dermatologist for proper diagnosis and treatment.

Horizontal nail lines
Causes of Beau's lines include:
- Illnesses or infections: Strep infections, high fever, heart attack, and skin conditions like eczema or psoriasis.
- Chronic conditions: Hypothyroidism, peripheral artery disease (PAD), Raynaud's phenomenon, and diabetes.
- Nutritional deficiencies: Zinc deficiency, iron deficiency, or a lack of protein in the diet.
- Emotional stress: Severe emotional stress, such as divorce, job loss, or a death in the family.
- Environmental factors: Prolonged exposure to certain environmental factors, such as extreme cold.
- Nail damage: Artificial nails, gel manicures, or trauma to the nail matrix, such as slamming your finger in a door.
If you notice Beau's lines, it is important to consult a healthcare provider to rule out any possible health conditions and determine the underlying cause. Treating the underlying cause will allow new, smooth nails to grow. This process can take about six months, and there is no guaranteed way to prevent Beau's lines from occurring. However, maintaining a healthy and balanced diet, as well as taking supplements if recommended by your healthcare provider, can help promote strong and healthy nail growth.

Nail abnormalities
Healthy nails are smooth, with consistent colouring. However, as you age, your nails may develop vertical ridges, and they may become more brittle. These changes are harmless. Marks on your nails can be caused by injuries, viral warts, infections, and certain medications.
- Leukonychia refers to non-uniform white spots or lines on the nail. This condition is usually harmless and caused by minor trauma. However, in some cases, it may be associated with poor health, nutritional deficiencies, infectious or metabolic diseases, or certain drugs.
- Mees' lines are transverse white lines that can indicate arsenic poisoning.
- Onycholysis occurs when the nail plate separates from the nail bed, causing a white discolouration. This can be due to infection, trauma, or the use of certain nail products.
- Pitting refers to small depressions or pits in the nail. It is commonly associated with psoriasis, a skin condition that causes dryness, redness, and irritation.
- Beau's lines are depressions that run across the fingernail and can indicate malnutrition, previous severe illness, injury, or exposure to cold temperatures.
- Clubbing is when nails thicken and curve around the fingertips, usually over a period of years. This may be caused by low oxygen levels in the blood and is associated with heart and lung diseases, as well as cancer.
- Koilonychia, or spoon nails, is when fingernails have raised ridges and curve outward. This condition may be associated with iron deficiency and, in some cases, anemia.
- Paronychia is an infection around the nail, often caused by a yeast-like organism called Candida, leading to inflammation and redness at the base of the nail.
- Yellow nail syndrome is characterised by thicker nails that grow slower than normal. The nail may lack a cuticle and may pull away from the nail bed.
- Hutchinson sign is a darkening of the cuticle associated with a pigmented streak and may indicate aggressive melanoma.
- Splinter haemorrhages refer to small bleeding spots under the nails, which may be a sign of endocarditis, especially in patients with a heart murmur and unexplained fever.
It is important to consult a doctor if you notice any persistent or concerning changes in your nails, as they can provide a valuable insight into your overall health.
